For the podcast this week, we discuss an article that looked into the effectiveness of blood flow restriction (BFR) training for endurance athletes. This paper showed that BFR endurance training rated the highest in perceived effort compared to traditional high intensity interval training (HIIT), meaning it resulted in the most discomfort by the end of the experiment. However, compared to normal HIIT training, BFR used less oxygen and these subjects had a lower overall HR. This means the BFR group did less work overall. These studies show that BFR can be used as an addition to your endurance training routines, but most likely traditional endurance exercises and HIIT will offer the most benefit.
